ABSTRACT:
A trigonometry calculator is programmed with four selectable calculations of unknown parameters of any plane triangle having three known parameters. The calculations accept known parameters of SIDE SIDE ANGLE, SIDE ANGLE SIDE, SIDE SIDE SIDE, and ANGLE ANGLE SIDE and from such inputs calculate unknown angles and sides. The calculator can also be programmed to make a series of calculations determining three unknown parameters for any plane triangle having three known parameters.
